We're dividing 98103508 by 345 
Our goal is to divide 98103508 by 345.

Moving on to step 1:
If we divide 9 by 345, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 345

Going ahead to step 2:
If we divide 98 by 345, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Take the next digit (1) from the dividend and append it to 98, then repeat: 981 / 345

Moving on to step 3:
345 can be fit into 981 2 times, resulting in a remainder of 291.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 291 after subtracting 690 from 981.
Bring next digit (0) of the dividend behind the 291 and repeat the process: 2910 / 345

Going ahead to step 4:
The number 345 fits into 2910 8 times, leaving a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 2760 from 2910 and we're left with 150.
Grab the next digit (3) from the dividend, add it to 150, then carry on: 1503 / 345

Advancing to step 5:
When dividing 1503 by 345, we get 4 with a remainder of 123.
The next digit of our result is 4. 
Result so far: 284.0
Subtracting 1380 from 1503 leaves us with 123.
Fetch the next digit (5) from the dividend, attach it to 123 and continue: 1235 / 345

Step 6:
345 goes into 1235 3 times with a remainder of 200.
Put 3 as the next digit of the answer. 
Result so far: 2843.0
Deduct 1035 from 1235 and we're left with 200.
Grab the next digit (0) from the dividend, add it to 200, then carry on: 2000 / 345

Moving on to step 7:
2000 divided by 345 is 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 28435.0
If we subtract 1725 from 2000, we get 275.
Grab the next digit (8) from the dividend, add it to 275, then carry on: 2758 / 345

Let's proceed to step 8:
The number 345 fits into 2758 7 times, leaving a remainder of 343.
Put 7 as the next digit of the answer. 
Result so far: 284357.0
If we subtract 2415 from 2758, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 9:
The number 345 fits into 3430 9 times, leaving a remainder of 325.
The number 9 becomes the next digit in our result. 
Result so far: 284357.9
Subtract 3105 from 3430 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 10:
If we divide 3250 by 345, we get 9 and a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 284357.99
If we subtract 3105 from 3250, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The quotient of the division is 284357.99, and the remainder is 0.145.
